Material class sorts technology materials by their basic physical category, such as a metal, an alloy or a polymer. Wikipedia defines stainless steel as "an iron-based alloy that contains chromium, making it resistant to rust and corrosion," a specific class distinct from a pure metal or a ceramic. This dimension groups materials that belong to the same basic material class.
